Hodgdon/IMR/Winchester has a pretty extensive database on their website.
I got this data from here.
http://data.hodgdon.com/cartridge_load.aspThe format doesn't show up well on this board but the link above is well put together.
It shows a starting charge for the 150 Gr. at 46 Gr. of H4895 and max. charge at 49.5 Gr. compressed.
35 Gr. looks awfully light.
Cartridge: 7.62 x 54R
Load Type: Rifle
